DRILL MATERIALS

• When drilling hard, smooth surfaces, use a center
punch to mark the desired hole location. This can
prevent the drill bit from slipping off-center as the
hole is started.
• When drilling metals, use a light oil on the drill bit to
keep it from overheating. The oil can prolong the life
of the bit and increase the drilling action.
• If the bit jams in the workpiece or if the drill falls,
stop to use the machine immediately. Remove the
bit from the workpiece and analysis the casuse of
the jam.
NOTE
This drill has an electric brake. When the switch
trigger is released, the chuck stops turning. When the
brake is functioning properly, sparks can be visible
through the vent slots on the housing. This is normal
and is the action of the brake.
WOOD DRILLING
For maximum performance, use high speed steel bits
for wood drilling.
1. Operate the machine at a very low speed to prevent
the bit from slipping off the starting point. Increase
the speed as the drill bit bites into the material.
2. When drilling through holes, put a piece of wood
behind the workpiece to prevent ragged or
splintered edges on the back side of the hole.
METAL DRILLING
For maximum performance, use high speed steel bits
for metal or steel drilling.
1. Operate the machine at a very low speed to prevent
the bit from slipping off the starting point.
2. Hold a speed and pressure which let cut without
overheating the bit. Apply too much pressure can:
Overheat the drill; Wear the bearings; Bend or burn
bits; and Produce off-center or irregular-shaped
holes.
3. When drilling large holes in metal, start with a small
bit, then finish with a large bit. Also, lubricate the bit
with oil to improve drilling action and increase bit
life.

MAINTENANCE

Do not let brake fluids, gasoline, petroleum-based
materials touch the plastic parts. Chemicals can cause
damage to the plastic, and make the plastic
unserviceable.
Do not use strong solvents or detergents on the plastic
housing or components.

screwdriver into the chuck of the drill to remove the
screw in a clockwise direction.
• The chuck body can now be unscrewed by hand in
a counterclockwise direction.
8.2

RETIGHTEN A LOOSE CHUCK

• Aline the chuck hole to the drill spindle and tighten
the chuck in a clockwise direction until the chuck
engages completely with a continuous click. At this
time, the chuck jaw is closed.
• Use a dexterous strength to loosen the chuck jaw
counterclockwise. Aline the screw with the hole of
spindle and insert a screwdriver into the chuck to
tighten the crew counterclockwise.
8.3

CLEAN THE MACHINE

The machine must be dry. Humidity can cause risks of
electrical shocks.
• Clear the unwanted material out of the air vent with
